摘　　要：采用航空涡轮发动机润滑油试验方法-热安定性和腐蚀性测定法对不同品牌的5mm^(2)/s航空润滑油进行试验,对试验后的金属片表面进行形貌与组成特征进行研究,研究结果显示,不同配方体系,在274℃的高温试验中,磷、硫添加剂的腐蚀特征明显,但在富含硫的配方体系中,磷元素的影响作用被大幅度削弱。Test methods for aerospace turbine engine lubricants:Determination of thermal stability and corrosivity were adopted to test 5 mm^(2)/s aerospace turbine engine lubricants of different brands.The morphology and composition characteristics of the metal sheet surface after the test were analyzed.The research results showed that the corrosivity characteristics of phosphorus and sulfur additives were obvious in the high temperature test at 274℃for different formulation systems,but in the sulfur-rich formulation system,the influence of phosphorus was drastically weakened.

关 键 词：5mm^(2)/s航空润滑油 热安定性 腐蚀性 抗磨添加剂
